Climbing robot melts and cools plastic to get its footing
We've seen plenty of robots scale walls over the years, from models that emit supersonic streams of air to gecko-inspired creations, but few can carry more than their own weight, much less handle rough terrain. Enter this unique Swiss-made machine, which handles both tasks with aplomb thanks to the rapid melting and cooling of its thermoplastic adhesive feet. Created by the whiz kids over at the Swiss Federal Institute of Technology, the plastic compounds in the contraption's tootsies melt at around 70 degrees Celsius (158 Fahrenheit), where they're tacky enough to stick and fill surface gaps. If the bot needs to take a step forward, a thermoelectric effect kicks in to cool the plastics down, detaching the foot in the process. Repeat the motion several times and you get a tiny climbing critter that's able to carry about six to seven times its own weight over complex surfaces, a feat that's sure to be of actual use someday. It's certainly more practical, though a lot less fun, than one that mixes cocktails. Go on after the break to see the little climber in action.
Google releases Course Builder, takes online learning down an open-source road
Google is well-known for projects with unexpected origins. It's almost natural, then, that the code Google used to build a web course has led to a full-fledged tool for online education. The open-source Course Builder project lets anyone make their own learning resources, complete with scheduled activities and lessons, if they've got some skill with HTML and JavaScript. There's also an avenue for live teaching or office hours: the obligatory Google+ tie-in lets educators announce Hangouts on Air sessions. Code is available immediately, although you won't need to be grading virtual papers to see the benefit. A handful of schools that include Stanford, UC San Diego and Indiana University are at least exploring the use of Course Builder in their own initiatives, which could lead to more elegant internet learning -- if also fewer excuses for slacking.
Paraswift climbs buildings, jumps, lives to tell the tale (video)
Looks like not even our parachuting jobs are safe from the robot onslaught. Disney Research and the Swiss Federal Institute of Technology have joined forces to bring the world Paraswift, a plucky little robot with a penchant for scaling buildings and a thirst for thrills. The team recently posted some video of the 'bot, which can climb a wall, deploy a parachute and then coast relatively safely to the ground. Paraswift is more than just a mechanical thrill-seeker, however -- the machine has a built-in camera that can be used to record footage for use in 3D models. Death-defying video after the break.
RoboEarth teaches robots to learn from peers, pour European fruit beverages (video)
It's not quite war-ready, but a new Skynet-like initiative called RoboEarth could have you reaching for your guide to automaton Armageddon sooner than you think. The network, which is dubbed the "World Wide Web for robots," was designed by a team of European scientists and engineers to allow robots to learn from the experience of their peers, thus enabling them to take on tasks that they weren't necessarily programmed to perform. Using a database with intranet and internet functionality, the system collects and stores information about object recognition, navigation, and tasks and transmits the data to robots linked to the network. Basically, it teaches machines to learn without human intervention. If the introduction of this robo-web hasn't got you thinking of end times, maybe this will do the trick: it's already taught one robot, the TechUnited AMIGO, to deliver a box of creamy fruit juice to a bedridden scientist. You can check out video of the newly appointed automated waiter after the jump.
Quadrocopters enter the Flying Machine Arena, must bounce a ping-pong ball to survive (video)
We don't need another hero. We don't need to know the way home. All we want is life beyond the Flying Machine Arena, a test ground at the Swiss Federal Institute of Technology (ETH) where quadrocopters can learn new abilities and stretch their fan blades without injuring too many scientists. One such new ability is juggling balls -- well, one ball, anyway. This particular quadrocopter has learned to identify a ping-pong ball and is quite adept at keeping it in the air while the robot itself stays flying. Interestingly the last project we heard about from ETH also involved table tennis, so hopefully the next one involves a full-scale humanoid player that won't stop hunting until it has crushed every opponent.
